WINDOW OR DOOR SCREEN.

SPECIFICATION forming part of Letters Patent No. 668,564, dated February19, 1901.

Application filed September 11, 1900- Serial No. 29,682. (No model.)

To all whom it may concern.-

Be it known that I, JAMESM. LINDSLY, a citizen of the United States,residing at Mount Auburn, in the county of Christian and State ofIllinois, have invented certain new and useful Improvements in Window orDoor Screens; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The invention relates to window or door screens.

The object of the invention is to construct a window or door screen insuch a manner as to permit the escape of flies or other insects, andthis is accomplished, preferably, by separating the upper edge of thescreenfrom the upper rail of the screen-frame, so as to form an exit,and provide this exit with a reflected light, so as to attract theinsects to that point, thereby more quickly ridding the house of them.

With this and other minor objects in View the invention consists ofcertain novel features of construction, combination, and ar rangement ofparts, as will be hereinafter more fully described, and particularlypointed out in the appended claim.

In the accompanying drawings, Figure 1 is an elevation of a portion ofthe outer side of the upper rail of a window-screen or screendoor havinga fragment of screen fabric attached thereto. Fig. 2 is a longitudinalsectional view through said rail and screen fabric on broken line 2 2,and Fig. 3 is a vertical sectional View through the same parts on brokenline 3 3.

Referring now more particularly to the drawings, 1 denotes the outerside of the upper rail of a window-screen or screen-door, and 2 thescreen fabric. The screen fabric may be attached to this rail on itsouter side in the usual manner, but to form exit-passages 3 for theescape of the insects within the room. The forming of these passages maybe accomplished by the employment of spacingblocks at, any desirednumber of which may be employed. To attract the attention of the fliesand direct their movement upward, I provide one or more reflectors 5,secured to the outer side of the rail, to reflect the light downward andinto the room. As it is a well-known fact that insects will alwaystravel toward the light, they will naturally be attracted by the lightfrom the reflector and in trying to reach that point on the screen willpass out through the exit-passages.

From the foregoing description, taken in connection with theaccompanying drawings,

thebonstruction and mode of operation of my improved window or doorscreen will be readily understood without a more extended explanation ofthe same.

Changes in the form, proportion, and minor details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having thus described my invention, what Iclaim, and desire to secure byLetters Patent, is-

The combination of ascreen-frame, a screen having its edge attachedthereto, spacingblocks for separating a portion of the screen from saidframe to form an insect-exit passage, and a reflector secured to saidframe above said exi-tpassage in a position to reflect the light throughsaid passage, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JAMES M. LINDSLY.
